Revision history for DBIx::Class
+ * Fixes
+ - Fix _dbi_attrs_for_bind() being called befor DBI has been loaded
+ (regression in 0.08210)

+ table failing on MySQL. Resolves oversights in the fixes for
+ RT#81378 and RT#81897

+ when a limit without offset is encountered
+ - Correctly recognize root source unqualified columns when

+ - Officially deprecate the 'cols' and 'include_columns' resultset
+ attributes
+ - Remove ::Storage::DBI::sth() deprecated in 0.08191
+
+ * Fixes
+ - Work around a *critical* bug with potential for data loss in
+ DBD::SQLite - RT#79576

+ - Fix incorrect warning/exception originator reported by carp*() and
+ throw_exception()
+
+0.08242-TRIAL (EXPERIMENTAL BETA RELEASE) 2013-03-10 14:44 (UTC)
+ * New Features / Changes
+ - Prefetch with limit on right-side ordered resultsets now works
+ correctly (via aggregated grouping)
+ - Changing the result_class of a ResultSet in progress is now
+ explicitly forbidden. The behavior was undefined before, and
+ would result in wildly differing outcomes depending on $rs
+ attributes.
+ - Scale back validation of the 'as' attribute - in the field
+ there are legitimate-ish uses of a inflating into an apparently
+ invalid relationship graph
+ - Warn in case of iterative collapse being upgraded to an eager
+ cursor slurp
+ - No longer order the insides of a complex prefetch subquery,
+ unless required to satisfy a limit
+
+ * Fixes
+ - Properly consider unselected order_by criteria during complex
+ subqueried prefetch
+ - Properly support "MySQL-style" left-side group_by with prefetch
+ - Fix $grouped_rs->get_column($col)->func($func) producing incorrect
+ SQL (RT#81127)
+
+0.08209 2013-03-01 12:56 (UTC)
+ * New Features / Changes
+ - Debugging aid - warn on invalid result objects created by what
+ seems like an invalid inheritance hierarchy
+
+ * Fixes
+ - Fix another embarrassing regression preventing correct refining of
+ the search criteria on a prefetched relation (broken in 0.08205)
+ - Fix incorrect callsite reporting by DBIC::Carp
+
+0.08208 2013-02-20 09:56 (UTC)
+ * New Features / Changes
+ - A bunch of nonsensically named arguments to the SQL::Translator
+ parser have been marked as deprecated (while still fully
+ supported)
+
+ * Fixes
+ - Fix duplicated selected columns when calling 'count' when a same
+ aggregate function is used more than once in a 'having' clause
+ (RT#83305)
+ - Prevent SQL::Translator::Producer::YAML from seeing the $dbh
+ in a potentially connected $schema instance (RT#75394)
+
+ * Misc
+ - Fixup our distbuilding process to stop creating world-writable
+ tarball contents (implicitly fixes RT#83084)
+ - Added strict and warnings tests for all lib and test files
+
+0.08241-TRIAL (EXPERIMENTAL BETA RELEASE) 2013-02-20 11:37 (UTC)
+ * New Features / Changes
+ - Revert to passing the original (pre-0.08240) arguments to
+ inflate_result() and remove the warning about ResultClass
+ inheritance.
+ - Optimize the generated rowparsers even more - no user-visible
+ changes.
+ - Emit a warning on incorrect use of nullable columns within a
+ primary key
+
+0.08240-TRIAL (EXPERIMENTAL BETA RELEASE) 2013-02-14 05:56 (UTC)
+ * New Features / Changes
+ - Rewrite from scratch the result constructor codepath - many bugfixes
+ and performance improvements (the current codebase is now capable of
+ outperforming both DBIx::DataModel and Rose::DB::Object on some
+ workloads). Some notable benefits:
+ - Multiple has_many prefetch
+ - Partial prefetch - you now can select only columns you are
+ interested in, while preserving the collapse functionality
+ (collapse is now exposed as a first-class API attribute)
+ - Prefetch of resultsets with arbitrary order
+ (RT#54949, RT#74024, RT#74584)
+ - Prefetch no longer inserts right-side table order_by clauses
+ (massively helps the deficient MySQL optimizer)
+ - Massively optimize codepath around ->cursor(), over 10x speedup
+ on some iterating workloads.
+
+ * Fixes
+ - Fix open cursors silently resetting when inherited across a fork
+ or a thread
+ - Fix duplicated selected columns when calling 'count' when a same
+ aggregate function is used more than once in a 'having' clause
+ (RT#83305)
+
+ * Misc
+ - Fixup our distbuilding process to stop creating world-writable
+ tarball contents (implicitly fixes RT#83084)
+ - Added strict and warnings tests for all lib and test files
+
+0.08206 2013-02-08
+ * Fixes
+ - Fix dbh_do() failing to properly reconnect (regression in 0.08205)
+ - Extra sanity check of a fresh DBI handle ($dbh). Fixes
+ connection coderefs returning garbage (seen in the wild)
+
+ * Misc
+ - Only allow known globals in SQL::Translator leak allowance
+ - General cleanup of error message texts - quote names/identifiers
+ for easier reading
+ - Stop t/52leaks.t from failing when AUTOMATED_TESTING=1
+
+0.08205 2013-01-22
+ * New Features / Changes
+ - The emulate_limit() arbitrary limit dialect emulation mechanism is
+ now deprecated, and will be removed when DBIx::Class migrates to
+ Data::Query
+ - Support for the source_bind_attributes() storage method has been
+ removed after a lengthy deprecation cycle
+ * Fixes
+ - When performing resultset update/delete only strip condition
+ qualifiers - leave the source name alone (RT#80015, RT#78844)
+ - Fix incorrect behavior on resultset update/delete invoked on
+ composite resultsets (e.g. as_subselect_rs)
+ - Fix update/delete operations referencing the updated table failing
+ on MySQL, due to its refusal to modify a table being directly
+ queried. As a workaround induce in-memory temp-table creation
+ (RT#81378, RT#81897)
+ - More robust behavior under heavily threaded environments - make
+ sure we do not have refaddr reuse in the global storage registry
+ - Fix failing test on 5.8 under Win32 (RT#81114)
+ - Fix hash-randomization test issues (RT#81638)
+ - Disallow erroneous calling of connect_info on a replicated storage
+ (RT#78436)

+ - ::Storage::DBI::source_bind_attributes() removed as announced
+ on Jan 2011 in 0e773352a
+
+0.08204 2012-11-08
+ * New Features / Changes
+ - SQLMaker now accepts \'literal' with the 'for' rs attribute as an
+ override to the builtin FOR options
+ * Fixes
+ - Fix unique constraint violations in Ordered.pm blanket movement
+ (RT#79773, rolls back short-sighted 5e6fde33e)
+ - Fix API mismatch between new_result() and new_related() (originally
+ broken by fea3d045)
+ - Fix test failure on perl 5.8
+ * Misc
+ - Much more extensive diagnostics when a new RDBMS/DSN combination is
+ encountered (RT#80431)
+
+0.08203 2012-10-18
+ * Fixes
+ - Really fix inadequate $dbh->ping SQLite implementation (what shipped
+ in 0.08201 tickled other deficiencies in DBD::SQLite itself)
+
+0.08202 2012-10-06
+ * Fixes
+ - Replace inadequate $dbh->ping SQLite implementation with our own,
+ fixes RT#78420

+ * New Features / Changes
+ - Issue a warning when DateTime objects are passed to ->search
+ - Fast populate() in void context is now even more efficient by
+ going directly through execute_for_fetch bypassing execute_array
+ - Fix update()/delete() on complex resultsets to no longer fall back
+ to silly row-by-row deletion, construct a massive OR statement
+ instead
+ - Allow complex update/delete operations on sources without a
+ primary key, as long as they have at least one non-nullable
+ unique constraint
+ - dbicadmin now better supports catalyst-style config files, by
+ unrolling 'config_info' hashkeys
+ - Multiple Improvements MSSQL over DBD::ADO

+ - Fix SkipFirst and FirstSkip limit dialects (Informix and Firebird)
+ - Fix "Skimming limit" dialects (Top, FetchFirst) to properly check
+ the order_by criteria for stability
+ - Fix "Skimming limit" dialects (Top, FetchFirst) to propagate
+ non-selected order criteria when part of a larger subquery

+ - Explicitly disable DBD::ODBC batch operations (as of DBD::ODBC 1.35)
+ for the following drivers too buggy to handle the optimized path:
+ - FreeTDS ODBC driver (when used with MSSQL)
+ - The Firebird ODBC driver
+ - The MSAccess ODBC driver
+ - Explicitly disable DBD::ODBC dynamic_cursors when using freetds 0.83
+ or later - they made enough ODBC incompatible changes making it
+ impossible to support sanely
+ - Explicitly disable SCOPE_IDENTITY queries and statement caching for
+ MSSQL on DBD::Sybase compiled against freetds 0.83 or later - way too
+ buggy
+ - Disable statement caching when using Sybase ASE and DBD::Sybase

+ of storage capabilities
+ - Fixed carp_once only emitting one single warning per package
+ regardless of warning content
+ - Test suite now can be safely executed in parallel (prove -jN
+ or HARNESS_OPTIONS=jN)

sets quote_char and name_sep appropriate for your RDBMS
+ - Add retrieve_on_insert column info flag, allowing to retrieve any

+ (an ill-fated attempt was made in 0.08127 to order intelligently)
+ - All limit dialects (except for the older Top and FetchFirst) are
+ now using bind parameters for the limits/offsets, making DBI's

+ sub-selects in the selectors list (correlated subqueries)
+ - Fix inconsistency between $rs->next with and without HRI when all
+ the "root" columns are in fact injected from the right rs side
+ - Fix the join optimizer to correctly preserve the non-multi path to
+ a multi relationship ( x -> might_have y -> has_many z )
+ - Fix object-derived custom-relationship resultsets to resultsources
+ with multilevel monikers (e.g. $schema->source('Foo::Bar') )
